3.7. The IP Group

The access attribute of the variable ipForwarding has been changed
from read-only to read-write.

In addition, there is a new column to the ipAddrTable object,

ipAdEntReasmMaxSize

which keeps track of the largest IP datagram that can be re-assembled
on a particular interface.

The descriptor of the ipRoutingTable object has been changed to
ipRouteTable for consistency with the other IP routing objects.
There are also three new columns in the ipRouteTable object,

ipRouteMask
ipRouteMetric5
ipRouteInfo

the first is used for IP routing subsystems that support arbitrary
subnet masks, and the latter two are IP routing protocol-specific.

Two new objects are added to the IP group:

ipNetToMediaTable
ipRoutingDiscards

the first is the address translation table for the IP group
(providing identical functionality to the now deprecated atTable in
the address translation group), and the latter provides information
when routes are lost due to a lack of buffer space.
